(S)-tert-Butyl 2-((tert-butoxycarbonyl)amino)-5-hydroxypentanoate CAS 90194-99-3

Description

Compared with other compounds in its class, the molecular weight of 289.37 g/mol gives (S)-tert-Butyl 2-((tert-butoxycarbonyl)amino)-5-hydroxypentanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (S)-tert-Butyl 2-((tert-butoxycarbonyl)amino)-5-hydroxypentanoate (CAS 90194-99-3), a certified reference material (molecular formula C14H27NO5, MW 289.37 g/mol) for analytical method development and quality control.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, (S)-tert-Butyl 2-((tert-butoxycarbonyl)amino)-5-hydroxypentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
